DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized, light-weight mounting structure for auxiliary parts for a traveling operation system, which is mounted on a front portion of an automobile.

[0002]

2. Description of the Related Art As shown in FIGS. 13 and 14, at the front of an automobile, between an engine room 7 and a vehicle interior 8 is provided.
A vertical dash panel 9 is provided. The dash panel 9 is, as shown in FIG.
2, a vertical flat portion 99 is provided. The flat portion 99 has a large number of mounting holes 910 for mounting travel operation auxiliary parts such as the brake booster 92 and the clutch master cylinder 93. Below that,
It has a shaft mounting hole 912 for mounting the sterling shaft 80.

As shown in FIGS. 13 and 14, when mounting the traveling operation auxiliary parts on the dash panel 9, the brake booster 92 and the clutch master cylinder 93 are directly inserted into the mounting holes 910 from the engine room 7 side. Mounted. On the other hand, the brake pedal 94 and the clutch pedal 95 to be attached thereto are attached from the side of the vehicle cabin 8 with the attachment brackets 941 and 951 attached. Thereafter, the steering shaft 80 and a reinforcing member (not shown) are mounted in the steering shaft mounting hole 912.

[0004]

[SUMMARY] However, the above prior art has the following problems. That is, it is necessary to assemble the traveling operation system auxiliary components for each component such as the pedal, the booster, and the clutch master cylinder from both the engine room 7 and the vehicle interior 8 side. In particular, a plurality of pedals must be assembled, and each pedal must be mounted on the dash panel 9 via a relatively large pedal bracket.

[0005] For this reason, the mounting work of each component is extremely complicated, and the workability is poor. Particularly, since the assembling work from the vehicle cabin side is performed in a narrow place, the working posture is deteriorated and the workability is deteriorated. The bracket 941 for mounting the brake pedal 94 is mounted on a dash panel 9 having a relatively large flat surface, as shown in FIGS. Therefore, it is difficult to secure the support rigidity of the pedal,
As a result, the brackets 941 and 9
51 must be increased to improve the rigidity of the pedal mounting portion.

On the other hand, the quality inspection and the function check of the traveling operation auxiliary parts can be performed only after all of the above-mentioned parts are assembled in the vehicle. As a result, the detection of a defective portion by quality inspection or the like is delayed, and quality control is hindered. The present invention has been made in view of such conventional problems, and has as its object to provide a small and light-weight mounting structure for a traveling operation system auxiliary component, which has excellent support rigidity.

[0007]

The present invention relates to a dash panel.
In a mounting structure for a traveling operation system accessory part including a traveling operation system accessory part including a pedal, a pedal bearing having a box shape is provided inside a box type pedal box.
The dash panel is provided with a bent part, and the pedal assembly is assembled with the pedal box.
The vehicle-mounted driving system accessory parts are mounted on the vehicle from the engine room to the bent portion of the dash panel or the vicinity thereof.

The most remarkable points of the present invention are the following four points. First, the pedal box was box-shaped. Next, pedals, with are the pedal assembly assembled in advance pedal box traveling operation system auxiliary devices such as clutch master cylinder, a pedal shaft portion Bae
Positioned inside the box shape of the dull box (see Fig. 1)
thing. In addition, the dash panel to which this pedal assembly is attached must have a bent portion, not a flat surface. Further, the pedal box of the pedal assembly is assembled near the bent portion of the dash panel from the engine room side.

As the bent portion, for example, there is an uneven portion provided on the dash panel. Examples of the box shape include a triangular prism made of metal or resin, a rectangular parallelepiped, and a polygon having an uneven portion as shown in each embodiment (see FIG. 1). The pedal assembly is constructed by assembling traveling operation auxiliary parts, such as a plurality of pedals, a booster, and a clutch master cylinder, in a pedal box in advance (see FIG. 1).

Further, as shown in a fourth embodiment, a part of the dash panel and the pedal box can be integrally formed in advance by a metal processing plate, a plastic molding process or the like. This makes it possible to reduce the number of attachment parts for the traveling operation system auxiliary parts.

The pedal assembly is attached to the dash panel. What is important here is that the pedal assembly is assembled at least partly in the vicinity of the bent portion 90 of the dash panel 9. Here, the vicinity of the bent portion means within 10 cm from the bent portion. If it exceeds 10 cm, the rigidity of the mounting portion of the pedal assembly may decrease.

[0012]

In the mounting structure of the traveling operation auxiliary parts according to the present invention, the pedal box has a box shape. Its <br/> For mounting structure Ru obtained with excellent pedal support rigidity.
Further, since the dash panel is not a flat plate but has a bent portion, the support rigidity of the pedals is improved in combination with the rigidity of the pedal box. In addition, the mounting structure can improve the support rigidity, thereby avoiding an increase in the size of the bracket for improving the support rigidity, and reducing the size and weight of the entire bracket. In addition, by making the pedal box into a box shape and assembling and assembling travel operation auxiliary parts,
Since the automatic mounting of the mounting structure by a robot or the like is facilitated, the mounting workability is improved.

Further, since the traveling operation system auxiliary parts are assembled in advance to the pedal assembly, an assembling operation with a good working posture can be performed, for example, on a sub-line. Thereby, the assembling workability is improved. Further, since the pedal assembly can be mounted on the dash panel from the engine room side where it is easy to work, the workability of mounting the traveling operation system auxiliary parts is improved.

Further, since the quality inspection and the function check can be performed in advance in the state of the assembly before the pedal assembly is assembled to the dash panel, the efficiency of quality control and the quality inspection accuracy are improved. Therefore, according to the present invention, it is possible to provide a small and lightweight mounting structure for traveling operation system auxiliary parts that has excellent support rigidity.
